Published in&nbsp;<a href=\"http:\/\/dx.doi.org\/10.1126\/scitranslmed.adp1934\"><em>Science Translational Medicine<\/em><\/a>, the findings could enable placebo-controlled treatment studies, previously hindered by the lack of objective measures for tinnitus severity.<\/p>\n\n\n\n<p>The study, led by Dr. Daniel Polley, focused on the sympathetic nervous system, the body&#8217;s &#8220;fight, flight, or freeze&#8221; mechanism, to identify outward signs of distress in tinnitus sufferers. The team recruited 97 participants, including 47 with tinnitus and 50 healthy controls. Using AI-powered software, they analyzed video recordings of participants reacting to sounds, detecting subtle facial movements and pupil dilation patterns linked to tinnitus severity.<\/p>\n\n\n\n<p>Key findings revealed that individuals with severe tinnitus exhibited exaggerated pupil dilation to all sounds, while their facial responses were blunted. In contrast, those with mild or no tinnitus showed stronger reactions only to unpleasant sounds. These biomarkers provided the most accurate measure of tinnitus distress to date, surpassing traditional questionnaire-based assessments.<\/p>\n\n\n\n<p>Dr. Polley highlighted the practicality of the approach, noting its potential for adaptation to consumer-grade electronics, which could revolutionize clinical trials and hearing health clinics.<\/p>\n\n\n\n<p>\u201cFor the first time, we directly observed a signature of tinnitus severity,\u201d said Dr. Polley. \u201cThese biomarkers reveal body-wide threat evaluation systems operating outside their normal range, leading to the distressing symptoms patients experience.\u201d<\/p>\n\n\n\n<p>The study\u2019s findings open new avenues for developing targeted therapies, such as combining neural stimulation with immersive software to alleviate tinnitus symptoms. Future research will include broader populations, such as those with hearing loss or mental health challenges, to further validate the biomarkers. This breakthrough marks a significant step toward objective, measurable solutions for tinnitus, a condition affecting millions worldwide.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers at Mass General Brigham have discovered new biomarkers for tinnitus by measuring involuntary facial movements and pupil dilation, which correlate with the distress caused by the condition.
